Key takeaway

GL 134B legalised the next Russian tanker into Cuba while the Florida revocation letter sat unanswered for 75 days.

US Treasury issued OFAC General Licence 134B on Saturday 18 April 2026, authorising transactions in Russian crude loaded before 17 April and running through 16 May. Treasury Secretary Scott Bessent justified the licence on grounds the oil was "already in transit" and would not deliver Russia "significant financial benefits". OFAC is the Office of Foreign Assets Control, the Treasury division that administers US sanctions. The cargo most directly covered is the Universal, a 50,923 DWT Sovcomflot tanker carrying roughly 700,000 barrels of crude expected at Matanzas around Wednesday 29 April.

GL 134B is the second consecutive 30-day wind-down extension from OFAC, following GL 134A on 19 March. It sits inside the EO 14380 sanctions architecture that took effect in late January and nominally authorises secondary tariffs against third countries shipping crude to Havana. Secondary tariffs are penalties Treasury can impose on insurers, banks and shipping firms doing business with sanctioned suppliers; a wind-down general licence narrows that exposure for the specific cargoes the licence names. The instrument lets enforcement claim a hard line in public while permitting transactions already in flight to settle.

A parallel Venezuela private-sector licence dated 25 March has moved no crude at all. The PDVSA carve-out from a sister Treasury action walled off Cuban state buyers from Venezuelan oil entirely, which means Sovcomflot tankers from the Baltic are now the island's last resupply line. The Florida congressional delegation that demanded a comprehensive licence purge in February has heard nothing back from Treasury for 75 days. Two consecutive wind-down extensions covering Sovcomflot deliveries signal an enforcement posture more permissive than the headline.

If a third extension follows in mid-May, the GL 134/A/B sequence becomes a de facto 60-day rolling licence for Sovcomflot deliveries to Cuba. Insurance and shipping markets will then price these extensions as predictable rather than exceptional, eroding the deterrent effect of secondary tariffs on subsequent Russian cargoes.

Deep Analysis

In plain English

The US Treasury has a division called OFAC that enforces sanctions. On 18 April it issued what is called a General Licence, a written permission slip telling shipping companies, insurers and banks that they will not be punished for handling a specific Russian oil cargo already loaded onto a ship. This is the second permission slip in a row, following one issued on 19 March. The permission directly covers the next Russian oil tanker heading to Cuba. Without it, every company involved in moving that ship would face US financial penalties. With it, the cargo is legally cleared through 16 May. The US government's public position is that Russia is not supposed to supply Cuba; the licence means that in practice, this particular delivery is allowed.

Deep Analysis

Root Causes

OFAC's general-licence tool exists precisely to manage the gap between a public sanctions posture and the operational reality of cargoes already loaded and financed. Once a tanker departs a Russian port with contracted crude, forcing a mid-ocean default would expose US banks and insurers to breach-of-contract liability under the contracts pre-dating the sanction. Treasury's legal risk calculus favours a wind-down licence over a mid-voyage default, independent of the political headline.

The PDVSA state carve-out in the 18 March licence removed Venezuela as Cuba's alternative supplier at the state level, making Sovcomflot deliveries the only available resupply route. Treasury cannot easily revoke GL 134B without triggering the grid failure that EO 14380's own humanitarian carve-out provisions are designed to prevent.

What could happen next?

Precedent
Two consecutive GL 134 extensions covering Sovcomflot deliveries to Cuba establish a renewable 30-day carve-out pattern that shipping and insurance markets will price as predictable, reducing the deterrent effect of EO 14380 secondary tariffs on future Russian deliveries.
Short term · 0.82
Risk
If Treasury declines to issue GL 134C in mid-May, Cuba's grid faces a supply cliff: the Universal's cargo covers approximately nine to ten days of demand, and no alternative supplier has a licensed route to the island.
Short term · 0.78
Consequence
The 75-day Treasury silence on the Florida-delegation revocation letter, combined with GL 134B issuance, weakens the delegation's standing as the operational anchor of the administration's Cuba sanctions posture.

Source Landscape

This story draws on neutral-leaning sources

Primary parallel: The US Iran nuclear-waiver sequence between 2018 and 2019 offers a structural parallel. After reimposing sanctions under JCPOA withdrawal on 5 November 2018, Treasury issued 180-day wind-down waivers to eight oil-importing nations.

Each waiver was justified as covering pre-contracted shipments already in transit. When the Trump administration declined renewal in April 2019, the deterrent finally bit. The GL 134A-to-134B sequence mirrors that architecture, with the key difference being that GL 134B covers a single vessel, not a national import programme.

Counter-parallel: The Obama-era Cuba sanctions wind-down after December 2014 normalisation moved in the opposite direction: licences expanded progressively over 24 months. That sequence ended in net liberalisation. The GL 134 sequence is contracting, but the two consecutive extensions make the contraction pace ambiguous.

GL 134B protects roughly $20-25 million in cargo value (700,000 barrels at approximately $70/bbl spot) from secondary-tariff exposure, in addition to shielding the Universal's P&I insurance club, the letters of credit from the financing bank, and the port-operator liabilities at Matanzas from US sanction risk. Each 30-day extension reduces the cost of the next Sovcomflot booking by removing insurer uncertainty.

The pattern signals to the shipping and insurance market that a Sovcomflot booking to Cuba carries a predictable 30-day legal clearance window. At Lloyd's and in the Scandinavian P&I clubs, that predictability is priced as near-zero sanction risk for cargoes loaded before the licence cut-off date, which is structurally different from what EO 14380's secondary-tariff language was designed to produce.

Consensus view: The Atlantic Council's Sanctions Lab assesses that consecutive 30-day wind-down licences covering the same supplier follow a documented Treasury pattern from the Russia-Ukraine waiver sequence of 2022-23: each extension is framed as operationally routine, but two consecutive extensions covering the same cargo category establish the instrument as a de facto rolling authorisation.

The Center for a New American Security (CNAS) reaches the same reading, noting that insurers and payment intermediaries price the GL 134A-to-134B sequence as a renewal expectation, which neutralises the deterrent function of EO 14380's secondary-tariff authority on that route.

Counter-view: The Cuban government and Moscow-aligned commentators argue the licences confirm that EO 14380 is not a genuine embargo but a pressure instrument calibrated to avoid disrupting Russian energy flows already contracted before the order took effect. On this reading, Washington has no intention of enforcing secondary tariffs against Sovcomflot while the Universal is already at sea.

Key tension: Whether Treasury issues a third extension in mid-May or allows GL 134B to expire without replacement, which is the single observable test of whether the wind-down architecture is genuinely time-limited or a rolling carve-out for Russian deliveries to Cuba.

Different Perspectives

UN General Assembly

The Assembly passed last year's resolution against the US embargo by 165 votes to 7, with 12 abstentions, and votes again on 28 October. That count is the baseline against which Havana's lobbying claims and Washington's pressure will be measured.

Mexican Navy (Secretaría de Marina)

A Mexican Navy team inspected Grace at Progreso and found fuel in its ballast tanks, according to the US Coast Guard. The account of Mexico's role comes from Washington; the Mexican government's own position on the stop is not on record in the sources reviewed.

Pedro Monreal, independent Cuban economist

Monreal says the gazette contains no rule for the exchange-house licence ADT 64 received, so nobody knows how a second firm could apply. He says a representative rate would need at least ten houses in five provinces, Havana included.

Prisoners Defenders and OCDH (Madrid-based exile monitors)

Prisoners Defenders counted a record 1,351 political prisoners at the end of September, and OCDH logged at least 344 repressive actions that month. OCDH asked the European Union on 11 September to investigate possible trafficking in Cuba's medical brigade in Italy.

Florida Attorney General James Uthmeier

Uthmeier announced a no-bond state warrant for Raúl Castro on 19 October over the 1996 Brothers to the Rescue shootdown, after reopening the state investigation last year. The four men killed flew for a Miami exile group, and the warrant restricts Castro's travel rather than reaching him in Cuba.

Cuban government (Foreign Minister Bruno Rodríguez Parrilla)

Rodríguez said on 21 October that Washington is pressing governments to abstain or leave the hall in the 28 October UN vote and called Florida's Raúl Castro warrant worthless. Havana is presenting its October oil and trade rules as openings and the US measures as an energy blockade.
